+---
+
+Demand: CUST-WP-0073-T02 needs a supervised agent identity on railiance01 that
+can observe cluster state without reaching credentials or writing anything.
+This repo owns the RBAC half. The earlier health-only candidate
+(`the-custodian/docs/changes/CUST-WP-0073/credential-boundary-r1/identity-rbac.yaml`)
+is superseded by the founder's 2026-10-20 decision.
+
+Founder decision (Bernd Worsch, 2026-10-20):
+
+- Namespace `custodian-agents`, ServiceAccount `custodian-agent`,
+  `automountServiceAccountToken: false`. No static token Secret.
+- Credentials are short-lived TokenRequest tokens issued by the supervisor.
+- ClusterRole `custodian-supervised-observer`: get/list/watch on namespaces,
+  nodes, pods, deployments/statefulsets/daemonsets/replicasets, services,
+  endpoints/endpointslices, ingresses, events (core + events.k8s.io),
+  persistentvolumeclaims, Argo CD applications/appprojects, CNPG
+  clusters/backups/scheduledbackups; get on `/version /healthz /livez /readyz`.
+- Explicitly not: secrets, configmaps, pods/log, pods/exec, pods/attach,
+  pods/portforward, serviceaccounts/token, nodes/proxy, any write verb, any
+  wildcard. Privileged actions go through the separate gated executor.
+
+Layout:
+
+- Manifests: `argocd/platform-addons/custodian-agents/`
+- Child Application (manual sync, pinned, no finalizer):
+  `argocd/railiance01/applications/custodian-agents.application.yaml`,
+  project `railiance-platform-addons` (already whitelists Namespace,
+  ClusterRole, ClusterRoleBinding, ServiceAccount).
+- Offline guard: `tests/test_custodian_agent_rbac.py`.
+
+The railiance01 root `railiance-apps-root` has no `automated` block, so a push
+to `main` changes nothing live. Going live is an attended founder action.
+
+## Token issuance (supervisor only)
+
+Recommended TTL 24h (shorter is fine; the API server may cap it via
+`--service-account-max-token-expiration`). Audience is the API server's own
+service-account audience, so the token works against the API and nothing else:
+
+```bash
+kubectl -n custodian-agents create token custodian-agent \
+  --duration=24h --audience=https://kubernetes.default.svc.cluster.local
+```
+
+The token is handed to the agent's restricted kubeconfig by the supervisor; it
+is never committed, logged, or stored in the State Hub. It cannot be renewed by
+the agent (no `serviceaccounts/token` grant).
+
+## Place the identity manifests and offline guard
+
+```task
+id: RPF-WP-0062-T01
+status: done
+priority: high
+```
+
+Namespace, ServiceAccount, ClusterRole and ClusterRoleBinding written; the
+pytest guard parses the kustomization and asserts read-only verbs, the exact
+curated resource set, no forbidden resource, no subresource, no wildcard, no
+Secret, no automount, and a manual pinned Application.
+
+## Place the pinned child Application
+
+```task
+id: RPF-WP-0062-T02
+status: todo
+priority: high
+```
+
+`custodian-agents.application.yaml` pins `targetRevision` to the commit that
+introduced the manifests. No `automated` block, no finalizer.
+
+## Attended sync and identity proof on railiance01
+
+```task
+id: RPF-WP-0062-T03
+status: wait
+priority: high
+needs_human: true
+blocking_reason: "Founder runs the attended root sync for the custodian-agents child, issues a token and runs the can-i proof; live production change."
+```
+
+1. `make argocd-pin-drift` — stop on any `DRIFT` line.
+2. Sync only this child out of the root at the reviewed revision, then the child
+   (commands in the CUST-WP-0073-T02 handoff / this repo's commit log).
+3. Issue a token (above) and, as the agent identity, prove:
+   `kubectl auth can-i get secrets -A` → no; `can-i create pods/exec -A` → no;
+   `can-i get pods/log -A` → no; `can-i get configmaps -A` → no;
+   `can-i list pods -A` → yes; `kubectl auth whoami` shows
+   `system:serviceaccount:custodian-agents:custodian-agent`, no `system:masters`.
+4. Report the result to CUST-WP-0073-T02.
